Targeted Weed Killer: Precision Foam Herbicide Delivery System

1,866 views

Published on

One of the biggest drawbacks of conventional herbicide application systems is that they cannot target weeds precisely. Green Shoots has introduced a revolutionary new herbicide delivery system that applies herbicides exactly where you want them - with dramatically reduced drift, overspray, or drip. The system can be used with foliar, cut surface, and wiping techniques. This presentation shows before and after photos demonstrating the effectiveness of the system.

Targeted Weed Killer: Precision Foam Herbicide Delivery System

  1. 1. Targeted Weed Killer – The Precision Foam Herbicide Application System from Green Shoots® By John Lampe January 17, 2014
  2. 2. Conventional herbicide application systems don’t work well if desirable plants are mixed with weeds Crown vetch invading a planting bed 2
  3. 3. Problems with conventional systems: • Spray systems: high pressure creates fine droplets which cause overspray and drift • Wiping systems: use absorbent materials that drip excessively and collect dirt and plant matter 3
  4. 4. What is the alternative? 4
  5. 5. Green Shoots Precision Foam Herbicide Application Systems Large Foam Herbicide Dispenser with Foliar Nozzle Large Foam Herbicide Dispenser with Extension Nozzle NOTE: Large Foam Herbicide Dispenser Available Starting March, 2014 5
  6. 6. Large Dispenser used for foliar application to highly invasive Japanese knotweed 6
  7. 7. NOTE ABSENCE OF FINE DROPLETS ON LEAF OR IN THE AIR! 7
  8. 8. Foam herbicide clings to foliage of invasive knotweed 8
  9. 9. Herbicide spreads on leaf 9
  10. 10. Herbicide slowly dries on leaf – increasing absorption 10
  11. 11. Stump and Cut Surface Applications – Nozzle Extension 11
  12. 12. Foam herbicide (triclopyr amine) applied to cut stump of invasive buckthorn 12
  13. 13. 1 Minute – Foam recedes but clings 13
  14. 14. 1 min. 18 sec: Foam herbicide gradually soaks into stump 14
  15. 15. 1 min. 40 sec: Foam herbicide almost completely soaked in with no drippage! 15

  17. 17. Use the Small Herbicide Dispenser for small, highprecision jobs like this cut stump application 17
  18. 18. What are the results? 18
  19. 19. Small amount of concentrated foam herbicide (glyphosate) applied to bull thistle rosette in lawn. . . 12 days later, the thistle is dead with no harm to grass even though glyphosate is a non-selective herbicide! 19
  20. 20. Small amount of concentrated foam herbicide (glyphosate) applied to invasive Canada thistle . . . 10 days later – thistle is dead. 20
  21. 21. Small Amount of concentrated foam herbicide (glyphosate) applied to invasive perennial sowthistle. . . 15 days later the sowthistle is dead. 21
  22. 22. Tangled mass of crown vetch in a planting bed 22
  23. 23. Small amount of concentrated foam herbicide (glyphosate) applied to bent stem base of crown vetch. . . 35 days later, crown vetch is dead with no re-sprouts. 23
  24. 24. Small amount of concentrated foam herbicide (glyphosate) applied to small weed tree. . . 18 days later – successful treatment 24
  25. 25. Small Amount of Concentrated One year later, the buckthorn stump Foam Herbicide (glyphosate) Is dead with no sprouting. applied to stump of invasive buckthorn. . . 25
  26. 26. Advantages of the Green Shoots Precision System • Less risk to desirable plants: less overspray or drippage • Herbicide uptake increased: foam herbicide sticks to and dries slowly on weed tissue • Visibility Improved: foam is easy to see • Reduced Herbicide Waste: only apply what is needed for the job 26
